meteohub.de

Hello,
i am going to connect a lufft weatherstation to meteohub. I take a look in the manual but there is no further information about how to connect or how to choose the parameters. For me its interesting to know what baudrate and what kind of protocol i have to select.

Best regards
The Weatherman

Lufft was connected via UMB and a serial connection.
Serial connection is 19.200 baud, 8 bit, no parity.

Ok, thanks. What kind of UMB protocol is used? The UMB binary (binär) or UMB ASCII?

when I remember correctly the ASCII one.

So i have tried to connect the station but there occurres an error. I have added the screenshots in the attachments.
In Meteohub i have not found the settings of the baudrate.

What does "Log Files" say? Section "meteohub log" should show reports form the data logger.
It is always a good idea to inspect log files, when something doesn't work...

The following Information is available in the meteohub protocol:

But on the top of every page there is a warning that no sensor is connected “Warnung: Der Wetterstation ist noch kein Sensor auf der Seite "Sensoren" zugewiesen”.

So I tried to create a new virtual sensor (I don`t know if this is required) and now these information is available in the meteohub protocol:

The information that the demo licence has timed out make no sense for me because on the System Info page is the information given that the demo version works for the next 280 days. “Eingeschräkte Demoversion, noch 280 Tage gültig”

Now i have rebootet the system (rpi) and then disconnected the weatherstation while the meteohub system was running again and connected after about a few minutes (look at the logfiles below). On the the serial device at the weatherstation i can see a status LED which is blinking shortly when a command is coming in. There is only a blinking when the meteohub connects to the station (bold marked text below). There is no poll command by the meteohob between that time.

To what ID is your UMB configured? These systems are not plug and play.
Did you connect it for testing and configuration with your PC? Does it work there?

Looking at the code I think that it is the binary format... sorry.

Thank you the protocol was the only problem!

My Lufft weatherstation has a built-in pyranometer that measures the global radiation (Globalstrahlung) and has the channel number 900. Is it possible to read out this parameter by myself (via virtual sensor or something like that)?

can you please send specs how to extract that data to "info(at)meteohub.de".

At the moment only these sensors are supported
{7, 100, 0}, // act temp celsius
{7, 110, 0}, // act dew celsius
{7, 200, 0}, // rel hum %
{7, 300, 0}, // act press hpa
{7, 305, 0}, // act sealevel press hpa
{7, 460, 0}, // average wind speed m/s
{7, 400, 0}, // act wind speed m/s
{7, 500, 0}, // wind direction degrees
{7, 700, 0}, // data (precipitation flag: 0 none, 60 ran, 70 snow)
{7, 600, 0}, // rain total mm
{7, 800, 0}, // rain rate mm/h

I added the solar radiation sensor. Which type of Meteohub hardware do you have?

I use a rasperry pi b+. Do you still need the specs to continue?

nope, just install update 5.0i again (I added some code for your station).
